627 Series Pressure Reducing Regulators - Emerson
www.emerson.comPressure is measured under the diaphragm through the 1/4 NPT downstream control line connection (Figure 2). Type 627BM: Direct-operated pressure reducing regulator with a balanced port and a stem seal between the body outlet pressure and diaphragm case. Pressure is measured under the diaphragm through the 1/4 NPT downstream control line connection.

documents.holley.comNOTE: If the pump is a high-pressure model, a pressure regulator must be installed in the line between the pump and the carburetor. NOTE: The mounting holes are untapped on these regulators. Use the supplied self-tapping screws. 1.
Regulator Product Line - Itron
www.itron.comProduct Line Designed for accuracy, dependability and safety, Itron gas pressure reducing regulators are for use in natural gas distribution systems as well as industrial applications (for example, burners and boilers) with most non-corrosive gases, including air, nitrogen, dry carbon dioxide and propane.
The Industry Standard for Pressure Regulators
www.emerson.comBackpressure regulators control the inlet pressure rather than the outlet pressure. The selection criteria for the backpressure regulator is the same as for a pressure reducing regulator. Relief Valves and Backpressure Regulators A pressure relief valve is a control device that opens to relieve fluid to atmosphere during an overpressure ...
SUCTION & LIQUID LINE SIZING CHARTS USING LINE SIZING …
www.hillphoenix.comThese line sizing charts are based on a suction pressure drop equivalent to a 2°F change in saturation pressure and liquid line pressure drop of 5 psi. For R-404A Low Temperature 1 psi; for R-404A and R-22 Medium Temperature 2 psi is used. This is the maximum allowable pressure drop for the entire piping run regardless if it is 50' or 250'.

The steam inlet pressure to the regulator must be higher than the required heat exchanger operating pressure to allow flow. The available steam pressure should be at least two times the heat exchanger operating pressure to provide modulation of the regulator for good temperature ...

Model 243 Service Regulators
marshallwnelson.comThe table below gives the pressure accuracies obtainable with 243-12 and 243-8 regulators at the capacities in the tables on pages 6 to 22. The 243 will hold outlet pressure within the indicated percentage limits from set flow (250 scfh) to the flows given in the capacity tables. Percentages are all based on absolute pressure using
